(NEW YORK) -- Mississippi police fear that a killer posing as a police officer is pulling over motorists late at night on dark highways and then shooting them.
Authorities suspect the shooter may be pretending to be a cop because the perpetrator may have been driving a white, unmarked Crown Victoria sedan, which can resemble a police car.
One driver, a 74-year-old Nebraska man, was found in his car on Interstate 55 in Panola County on May 8 about 1:30 a.m. A 48-year-old Mississippi woman was found near her car on Mississippi Highway 713 in nearby Tunica County about 2:15 a.m. -- three days later.
The shootings appear to be random and there is no known connection between the victims. The Nebraska man was en route to Florida to get his grandson, and the female victim worked at nearby casino. Police are analyzing shell casings discovered at both scenes.
Authorities have launched a dragnet; saturating the area, looking for clues and a possible suspect.
